MULTIPLE FOUNTAIN PEN.

Application filed March 5, 1921. Serial No. 449,958.

To all whom it may concern.

Be it known that I, LAWRENCE L. Houses, a citizen of the United tates,residing at idishawaka, in the county of St. Joseph and State ofIndiana, have invented certain new and useful Improvements in MultipleFoum .uiu Pens, of which the following is a specification.

The invention relates to multiple fountain pens and has for its objectto provide a device of this character comprising a cylindrical bodymember having a substantially centrally disposed partition thereinthereby forming parallel chambers in the body member, in one of whichchambers a longitudinally movable fountain pen is disposed and slidable,and the other chamber forming a reservoir for a non-movable pen whichprojects from one end of said chamber. Also to provide means whereby themovable pen may be held in retracted position in its chamber or inextended position.

A further object is to providev a multiple fountain pen particularlyadapted for book keepers and draftsmen and in other occupations wheretwo colors of ink are neces sary, for instanceblack and red ink.

it further object is to providea screw cap for the rear end of thecylindrical body member which sore Y cap houses filling opening closuresin the movable pen and the reservoir of the fixed pen.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a view in elevation of the pen.

Figure 2 is a vertical sectional view taken on line 22 of Figure 1.

Figure 3 is a plan view of the rear end of the pen, showing the samewith the cap removed therefrom.

Referrin to the drawings, the numeral 1 designates a cylindrical bodymember and 2 a partition extending through said body member, whichpartition is centrally disposed thereby dividing the chamber of the bodymember 1 into semicircular chambers 3 and at. The chambers 3 and 4extend substantially the full length of the body memher 1, however thesemicircular chamber 3 forms reservoir for the reception of ink I andinto which reservoir ink is placed through the apertured upper end 5which is normally closed by a threadedplug 6. The lower ends of thesenilcircular chambers 3 and 1 taper and disposed 1n the lower end ofthe chamber 3 is a conventional form of fountain pen feeding plug 7which carries the fountain pen 8. It will be seen that the pen point 8is a fixed one and the ink most commonly used, for instance black,"isplaced in the chamber 3, therefore for ordinary work the bookkeeper ordraftsman would use this pen.

Slidably mounted in the semicircular I? k chamber ,4 is a semicircularshaped casing 9 which casing is provided with a chamber 10 forming anink reservoir, into which ink is placed by removing the plug 11 in theupper end thereof. The lower end of the casing 9 is tapered as. at 12 atsubstantially the same angle as the lower end of the chamber 4: therebyproviding means whereby the cars ing 9 will be limited in its outwardmovement, said lower end offthe casing 9 being provided with aconventional form of pen point 18, which when-the casing is forceddownwardly assumes the position shown in Figure 2 and in which positionthe lower end of the pen point 13 will project beyond the pen point 8and be in a position where it can be used for writin or drawing lines.The ink placed within the reservoir 10 is preferably red, however it maybe of any color desired. Secured to the casing 9 as at 1 1 is a leafspring 15 which leaf spring extends upwardly through an elongated slot16- in the cylindrical body 1 and adjacent its free end is provided withspaced prongs 17, which prongs when the casing 9 is in the positionshown in Figure 2 engages apertures 18 in the outer periphery of thecylindrical casing 1 and holds the casing in retracted position as shownin Figure 2. When the prongs 17 are disposed in the apertures 18 theupper end of the casing 9 is flush with the upper end of the cylindricalcasing 1 and .is in a position where the plug 11 may be easily removedwhen the cap 19 is removed, thereby facilitating the filling of thereservoir 10. When the casing 9 is extended after pulling outwardly onthe leaf spring 15 by grasping the knob 20 and forcing downwardly on thesame, said casing is held in proper extended position and the pen 5 Fromthe above it will be seen that a multiple fountain pen is provided,which is sim ple in construction and one wherein the movable pencomprises a longitudinal movable casing having a reservoir therein and apen,

which penand reservoir comprise a single unit, thereby obvlatlng leakingwhich is common in pens of this character and also reducing the parts toa minimum and sim-:

plifying the construction. a

The invention having been set forth what is claimed as new and usefulis 1. A multiple fountain pen comprlsmg a casing having longitudinallydisposed semicircular chambers therein, a pen point extending from oneend of one of said cham bers, the upper end of the chamber having thepen point having a closed filling opening, a longitudinally movablefountain pen casing disposed in the other semicircular chamber, a penpoint carried by one ,endof said longitudinal movable casing, a closedfilling opening carried by the upperend ofsaid longitudinally movablecasing, a leaf spring having one of its ends secured to the longitudinalmovable casing, said leaf spring extending upwardly and outwardlythrough anelongated aperture in the main casing, the free end of saidleaf spring being pro vided with prongs, said prongs being adapted toengage aperturesin the outer periphery of the casing for holding thelongitudinal movable casing in extended or retracted position.

2. A multiple fountain pen comprising a cylindrical casing havinglongitudinally disposed chambers therein, a fixed pen-point carried byone of said chambers, a longitudinally movable fountain pen unitslidably mounted inthe'other chamber, means for holding thelongitudinally movable fountain pen unit. in retracted or extendedposition,

The combination with a fountain pen.

having a reservoir within a casing, a pen point at one end of saidcasing and a closed filling opening at the other end thereof, of anauxiliary casing carried by said-casin said auxiliary casing having alongitudinally movble fountain penunit slidably mounted in a chamberthereof, a filling opening at the upper endof said fountain pen'unit, apen point at the other end of said fountain pen unit and means forholding said fountain pen unit in extended or retracted position, saidmeans forming means whereby when the fountain pen unit is in retractedposition the filling opening thereof will be in the same transverseplane as the filling openingof the main casing.

In testimony whereof I affix m signature.
